Pete H Posted August 15, 2020 Share Posted August 15, 2020 I will start a build thread when all the parts arrive and lay it all out there. When I take it to SWAG in September, that's when we can get subjective listening and measurement data against some others and see. Quote Link to comment Share on other sites More sharing options...
Pete H Posted August 15, 2020 Share Posted August 15, 2020 Actually, when I get to @CECAA850 place right before SWAG, we can run it there against a 684 and I will do a little comparison prior to leaving, if given enough time. Quote Link to comment Share on other sites More sharing options...
Khornukopia Posted August 15, 2020 Share Posted August 15, 2020 I watched the cabinet assembly video on the GSG website link. Looks like a well made flat pack kit. Should be a good heavy duty subwoofer when properly built. Quote Link to comment Share on other sites More sharing options...

I'm sure @diamonddelts will chime in with that direct comparison. I'm very curious as well. Who do we know that has an 1802 and can haul it to Hope?

LTD02 Posted August 17, 2020 Share Posted August 17, 2020 (edited) Hey guys, I saw there was some question about performance on the Devastator vs. a horn with an increasing flare. In order to shed some light on that one, I went ahead and modeled the Devastator and a second Devastator with an increasing flare rate (2:1 ratio for the mouth-to-throat cross-sectional area), approx. a 2:1 compression ratio, and the same size horn mouth. This isn't the only possible horn of course, but it is a decent starting point for seeing some of the issues involved. Both cabs have identical drive voltage 2.28 volts, which when considering the driver's DC resistance of 5.2 ohms, equals 1 watt of power. Simulation is 2pi space for both cabs as well. Below is the 1w1m response of both horns. Devastator is the one on top. It can be seen that the Devastator has greater output than the flared port horn from 50-80Hz, while the flared port horn has greater output above 85Hz. The second chart shows the efficiency of both cabs. Again, Devastator is the one on top. The Devastator's peak efficiency occurs at just over 80Hz, while the flared port horn peaks at about 100Hz. From these charts, the Devastator has greater output and efficiency up to about 85Hz. Since most folks are interested in bass from the teens on the low end up to about 100Hz on the upper end, the horn with zero flare offered superior performance across a larger portion of the frequency range of interest than the flared horn. The horn path on the Devastator was optimized for performance first. An unintended consequence of the optimization was that the horn path didn't require flaring. This made it super easy to DIY. If it was only easy to build, but didn't perform, it wouldn't have taken off like it did (either as a DIY project or as GSG flat pack kits). I've designed many horns over time, all with performance as the primary objective. 🙂 This one just so happened to be both optimized for performance and ease of construction, both at the same time. That rarely happens, but in this case it did. So, please don't feel like the Devastator is compromised with respect to performance simply because its flare rate is zero and is an easy build. Hope that helps. John Edited August 17, 2020 by LTD02 4 Quote Link to comment Share on other sites More sharing options...
